Selelekela PCIe 6.0

PCI-SIG Organisation e phatlalalitse tokollo ea semmuso ea PCIe 6.0 standard standard v1.0, e phatlalatsang hore e phethetsoe.

Ha re ntse re tsoela pele ka kopano, lebelo la bandwidth le tsoela pele ho imena habeli, ho fihla ho 128GB/s(unidirectional) ho x16, mme kaha theknoloji ea PCIe e lumella phallo ea data e felletseng ea duplex, kakaretso ea litsela tse peli ke 256GB/s.Ho ea ka morero, ho tla ba le mehlala ea khoebo ea 12 ho ea ho likhoeli tse 18 ka mor'a ho phatlalatsoa ha maemo, hoo e ka bang 2023, e lokela ho ba sethaleng sa seva pele.PCIe 6.0 e tla fihla bofelong ba selemo qalong, ka bandwidth ea 256GB/s.

Ho khutlela thekenoloji ka boeona, PCIe 6.0 e nkoa e le phetoho e kholo ka ho fetisisa historing ea PCIe ea lilemo tse ka bang 20.Ho bua 'nete, PCIe 4.0/5.0 ke phetoho e nyane ea 3.0, joalo ka khouto ea 128b/130b e thehiloeng ho NRZ (Non-Return-to-Zero).

PCIe 6.0 e fetohetse ho PAM4 pulse AM signing, 1B-1B coding, lets'oao le le leng e ka ba li-encode tse 'ne (00/01/10/11), tse habeli tse fetileng, tse lumellang ho fihla ho 30GHz frequency.Leha ho le joalo, hobane lets'oao la PAM4 le fokola ho feta NRZ, le na le mochini oa ho lokisa liphoso oa FEC pele ho lokisa liphoso tsa sehokelo le ho netefatsa botšepehi ba data.

Ho phaella ho PAM4 le FEC, theknoloji e kholo ea ho qetela ho PCIe 6.0 ke tšebeliso ea FLIT (Flow Control Unit) e kenyelletsoeng boemong bo utloahalang.Ha e le hantle, PAM4, FLIT hase theknoloji e ncha, ho Ethernet 200G + ultra-high-speed Ethernet e 'nile ea sebelisoa ka nako e telele, eo PAM4 e ileng ea hlōleha ho fana ka ts'ebetso e kholo ea lebaka ke hore litšenyehelo tsa lera la' mele li phahame haholo.

Ntle le moo, PCIe 6.0 e lula e lumellana le morao.

PCIe 6.0 e ntse e tsoela pele ho imena habeli I / O bandwidth ho 64GT / s ho ea ka moetlo, e sebelisoang ho PCIe 6.0X1 bandwidth ea sebele ea 8GB / s, PCIe 6.0 × 16 unidirectional bandwidth ea 128GB / s, le pcie 6.0 × 16 li-bandwidth tsa bidirectional tsa 256GB/s.PCIe 4.0 x4 SSDS, e sebelisoang haholo kajeno, e tla hloka PCIe 6.0 x1 feela ho e etsa.

PCIe 6.0 e tla ntšetsa pele khouto ea 128b/130b e hlahisitsoeng mehleng ea PCIe 3.0.Ntle le CRC ea mantlha, hoa thahasellisa ho hlokomela hore protocol e ncha ea mocha e boetse e tšehetsa khouto ea PAM-4 e sebelisoang ho Ethernet le GDDR6x, e nkela PCIe 5.0 NRZ sebaka.Lintlha tse ling li ka kenngoa mocha o le mong ka nako e lekanang, hammoho le mokhoa o fokolang oa ho lokisa phoso ea data o tsejoang e le ho lokisa phoso ea pele (FEC) ho etsa hore bandwidth e ntseng e eketseha e khonehe ebile e ka tšeptjoa.
